LFF Atomic Clock LWC204 Large Display Black 7.48 in x 1.5 in x 8.66 in

Large Atomic Display Clock

The LFF Atomic Clock LWC204 is a digital wall clock with a 7.48 in x 8.66 in LCD screen showing oversized digits for easy reading across a room. It displays indoor and outdoor temperature in Celsius or Fahrenheit, the date, day of week, and offers both 12 and 24 hour time modes. The unit is designed for bedrooms, offices, or living areas where clear visibility is a priority. Battery operation allows placement anywhere without a nearby power outlet.

WWVB Radio Synchronization

The clock contains a built-in receiver that locks to the WWVB signal broadcast from Fort Collins, Colorado, keeping time accurate to within one second through daily automatic updates. This atomic synchronization eliminates manual setting for daylight saving changes or power interruptions. The feature functions only where the WWVB signal is receivable, so buyers in regions outside the continental US coverage area cannot rely on automatic time correction.

Wireless Sensor and Dual Alarms

A wireless outdoor sensor is included, transmitting temperature data from up to 330 ft away without wiring, letting users monitor patio or garden conditions from indoors. The main clock requires three AA batteries and the sensor requires two AAA batteries, none of which are supplied. Dual alarms with a snooze function support separate wake times, while a low-battery indicator on the display warns when replacement is needed. Note that the display has no backlight.
